MOTOR FOR CHURNS.

SPECIFICATION forming part of Letters Patent No. 447,670, dated March 3, 1891. Application filed September 12, 1890. Serial No. 364,762. (No model.)

To all whom it may concern.-

Be it known that I, LOUIS S. EAVEs, a citizen of the United States, residing at Polkville, in the county of Cleveland and State of North Carolina, have invented a new and useful Motor for Churns, of which the followingis a specification.

This invention has relation to motors for churns the dashers of which are adapted to be reciprocated; and the objects and advantages of the invention, together with the novel features thereof, will be hereinafter described, and particularly pointed out in the claim.

Referring to the drawings, Figure 1 is a perspective of a churn-motor constructed in accordance with my invention. Fig. 2 is a longitudinal vertical section of the same. Fig. 3 is a transverse section.

Like numerals of reference indicate like parts in all the figures of the drawings.

The frame-work consists of two opposite vertical end pieces 1, serving as standards and each provided with an opening 2, said standards being connected by a pair of side bars 3. Near one end of the frame-work and upon the upper edge of the side bars there is mounted a pair of bearings 4, in which is journaled an operating-shaft 5, the central portion of which is squared, and upon the same there is fixed a pairof disks 7, connected at intervals by pins or bolts 8, upon each of which is mounted a frictional roller 9. The shaft is provided with and operated by a removable crank 10. A cleat 11 is secured to the outer surface of the opposite standard, to which it is secured by means of staples 12, the lower edge of the cleat resting upon and being supported by the adjacent ends of the side bars 3, which are projected and shouldered or recessed, as at 4:, for the reception thereof. A square opening 14 is formed in the cleat and in the same terminates the squared shank 15 of a spring-pawl 16, in this instance formed of a strip of suitable wood out to form a spring, the opposite end of the pawl terminating between the disks and adapted to be engaged by the friction-rollers mounted upon the bolts. Near the free end of the pawl or spring is formed an opening 17, in which is pivoted a loose depending link 18, bifurcated, as at 19, at its lower end and pivotally connected by a bolt 20 to the upper end of the dasher-rod. A frame 21 is secured to the under edges of the side bars 3 and is provided with a pair of vertically-opposite guides 22, in which reciprocates the dasher.

The operation of my invention is as follows: By revolving the shaft through the medium of the crank the friction-rollers are successively brought into contact with and raise the free end of the spring-pawl, and after they have passed from under the said end the spring nature of the pawl serves to lower the same, where it is caught by the next succeeding roller. By this a constant and uniform series of reciprocations are given the dasherrod, which, it will be understood, depends into the churn and may be provided with any suitable construction of head.

Having thus described my invention, I claim In a churn-motor, the combination, with the opposite vertical end standards having openings and the opposite parallel side bars connecting the standards and having their opposite ends projecting beyond one of said standards and shouldered or recessed, of bearings mounted on the upper edges of the bars, a shaft mounted in the bearings and having a central squared portion and a crank for revolving the same, opposite disks mounted on the squared portion between the bearings, bolts connecting the same and provided with friction-rollers, a spring-pawl the shank or rear end of which is squared, a cleat secured to the standard and resting in the recesses of the side bars and having an opening corresponding in shape and adapted to receive the squared shank, the opposite end of the pawl terminating between the disks and in the path of the friction-rollers and provided with an opening near its end, a link pivoted loosely in the opening and bifurcated at its lower end, a dasher-rod loosely pivoted at the upper end of the link, and a frame secured to the under edges of the bars and provided with opposite vertical guides, substantially as specified.

In testimony that Iclaim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
